Private Common Data Classes

With the function New Common Data Class it is possible to define own Common Data Classes or to extend existing CDCs. Thereby the new elements will be written into a private database. This elements then will be available for every new configuration.

If you apply a new Common Data Class it is possible to include further Sub Data Objects in addition to the attributes. Therefore, you have the possibility to select a CDC at the bottom of the window. For the attributes you can select the data types of the IEC 61850. This could be an integer for example. To describe the exact size of the integer there is a selection for the respective data type under ACSI Data Types. The Functional Constraints and the Trigger Option can be set as well. In the column Presence you can set if the element should be activated per default or should be optional.

In this graphic the in the standard defined CDC INC (Controllable Integer) is extended user-specifically. Therefore, you can select a Template for a CDC at the upper right side of the window. In order to avoid a conflict, the name of the CDC needs to be another than the name of the template.

By confirmation with the Add Button the new Common Data Class will be written into the private database and is available for the configuration.
